Cue everyone with crap wanting 500K... :roflol:
I agree these are very special cars though. I've said many times, it is my favourite BMW. The one Elton was selling in particular, for 250K is a hell of a car. Even the E60 I am tempted to get into. The good cars (like with all communities nowadays I guess) will have to trade hands in a 'known space'. The cars that end up at dealers, abused or even worse: at auction are high risks IMHO.
People are about to wake up to a few such cars very soon (I have some guesses).
On the newer cars, you can count on desperation to get into something new or out of the finance in order to hunt down a deal. With these older cars, it is going to get progressively harder as good owners won't want to sell in a hurry whilst others let the car rot/deteriorate whilst insisting on getting top dollar. Buying one without cash is also going to get harder as times get tougher... If you want to get one, act quickly!
